SOLUTION:

To begin with, let's establish the problem as the following:

5 + 7

An effective method to solve this problem would be to convert it into a visual representation in order to obtain a better understanding.

As attached in the diagram above, I have demonstrated the problem visually. The five red circles / dots represent the five in the problem whilst the 7 circles / dots represent the 7 in the problem. Now we must simply count each of the circles / dots to obtain the total number which would be our final answer.

We can also simply use our fingers on our hands to solve the problem by counting 5 on our fingers and then adding 7 or vice versa to obtain the final answer.

FINAL ANSWER:

Hence, through either of these two methods, we obtain the final answer to the problem as follows:

5 + 7 = 12

Hope this helps! :)
Have a lovely day! <3

A company orders supplies from M distributors and wishes to place n orders (n &lt; M). Assume that the company places the orders
harkovskaia [24]

Answer:

a) 0.06048 b) 0.001344 c) 0.000294

Step-by-step explanation:

number of distributors = 10;

number of orders = 7

a)

There are 10 distributors for each order, so the no. of ways the 7 orders could be placed are = 10⁷ =10000000

no. of ways that orders goes to different distributors = ¹⁰C₇*7! = 604800

Probability = 604800/10000000 = 0.06048

b)

number of ways distributor 1 gets exactly 2 and distributor 2 gets exactly 3 orders = ⁷C₂*⁵C₃*8² = 13440

probability = 13440/10000000 = 0.001344

c)

number of ways distributor 1, 2,3 get exactly 2,3 and 1 order(s) = ⁷C₂*⁵C₃*²C₁*7¹ = 2940

probability = 2940/10000000 = 0.000294

describe and correct the error a student made in finding the interval(s) over which the function is positive and negative
liraira [26]

Answer:

The interval over which the function is positive is (-1 , 3)

The interval over which the function is negative is (-∞ , -1)∪(3 , ∞)

Step-by-step explanation:

* Lets explain the meaning of The intervals of positive and negative

 values of a function

- Interval of positive values means the values of x when the values

 of y are positive

- Y is positive means the graph is above the x-axis

- Interval of negative values means the values of x when the values

 of y are negative

- Y is negative means the graph is below the x-axis

- <u><em>Remember</em></u> that the value of y on the x-axis is zero, then the points

 of intersection between the graph and x-axis have zero value of y

 and zero is not positive nor negative, then the x-coordinate of

 these points do not belong to the intervals of positive or negative

* <em>Lets solve the problem</em>

∵ The graph represents a downward parabola

∵ The positive value of the parabola is above the x-axis

∵ The parabola intersects the x-axis at -1 , 3

∴ Y is positive at ⇒ -1 < x < 3

# -1 , 3 ∉ to the interval

∴ The interval over which the function is positive is (-1 , 3)

∵ The negative value of the parabola is below the x-axis

∵ The parabola intersects the x-axis at -1 , 3

∴ Y is negative at ⇒ -∞ < x < -1 and 3 < x < ∞

# -1 , 3 ∉ to the interval

∴ The interval over which the function is negative is (-∞ , -1)∪(3 , ∞)

* <u><em>The error of the student he wrote Positive</em></u>: [-1 , 3] which means

  that -1 , 3 ∈ to the intervals over positive

  which the function is positive or negative
